cyberstrikeus IR-9(3) Post-spill Operations
Enhancement of: IR-9
High-Level Description
Family: Incident Response (IR) Framework: NIST SP 800-53 Rev 5
Corrective actions for systems contaminated due to information spillages may be time-consuming. Personnel may not have access to the contaminated systems while corrective actions are being taken, which may potentially affect their ability to conduct organizational business.
What to Check
- Verify IR-9(3) Post-spill Operations is documented in SSP
- Confirm control is operating effectively
- Review evidence of continuous monitoring for IR-9(3)
- Verify enhancement builds upon base control IR-9
How to Test
Step 1: Review Documentation
Examine the System Security Plan (SSP) and related artifacts for IR-9(3) implementation details. Verify the organization has documented how this control is satisfied.
Step 2: Validate Implementation
# For cloud environments, use cloud-audit-mcp tools
# For on-premises, review system configurations directly
# Example: Check if account management policies exist
grep -r "account.management\|access.control" /etc/security/ 2>/dev/null
Step 3: Test Operating Effectiveness
Verify the control is actively functioning, not just documented. Check logs, configurations, and operational evidence.
